Students warm to Atag boilers

28 January, 2008

The performance of heating systems in student halls of residences at the University of Warwick is being improved by installing Atag condensing boilers.

Heating boilers in student halls of residence throughout the central campus of the University of Warwick are progressively being replacing with Atag E Series condensing boilers to reduce fuel costs and carbon footprint. Alan Powell of the estates department explains, ‘The use of condensing boilers made sense because the efficient use of natural resources leads to greater economy and helps reduce our carbon footprint. The campus is divided into many separate residential blocks, each with their own heating and hot-water services. The most sensible route was to make direct replacement of the existing boiler in each residence with new and beneficial technology. The Atag E Series proved to be an ideal choice, being compact and easy to install in what are fairly restricted spaces.’ Initially, 12 halls have been converted, each with 12 student bedrooms, two bathrooms, kitchen and toilets. Each hall has a 32 kW wall-hung boiler with a horizontal flue through the wall. Condensate is piped to a soakaway. There is a high-capacity cylinder for storing hot water. Sensors are fitted to external walls to provide weather-compensated control. These boilers have inverted ceramic burners and smooth-tube stainless-steel heat exchangers, They can achieve an efficiency of 109.9% net with carbon-monoxide emissions of 24.8 mg/kWh and NOx of 22.3 mg/kWh. Installation was carried out by the university’s own mechanical-services engineers and included all ancillary electrical work.
